Title: Method of and apparatus for making longitudinally partitioned tubular container assemblies
IPC: H05B6/02
Filed: 1974-11-13
Abstract: 1491052 Forming tubes PROCTER & GAMBLE CO 13 Nov 1974 [13 Nov 1973] 49155/74 Heading F2P [Also in Divisions B3 B5 and B8] A partitioned tubular body 50 is formed by spindling a single sheet to provide a tubular wall and an integral chordal partition 61, opposite edge portions 62 and 63 of the sheet being heat-sealed to circumferential extending portions of the wound sheet adjacent the side edges of the partition to form longitudinal seams 64 and 65. The sheet is spindled on a longitudinally-slotted mandrel 220, the sheet being inserted through the mandrel slot until the leading edge abuts a guide 25, Fig. 12 (not shown). The mandrel is rotated, and pivoted rollers 222 co-operate therewith to wind the sheet, Figs. 8-17 (not shown). A thermoplastics head-piece may be initially fitted over the mandrel end when a collapsible tube is to be formed. The mandrel and wound sheet are then swung up against a fixed induction-welding jaw 256 and clamped thereagainst by pivoted induction welding jaw 255 which are energizable to form the seams 64 and 65. The mandrel is provided with a row of vacuum ports 236 (Fig. 8), which hold the free end portion of the wrapped sheet prior to welding. The body partition may be asymmetrically arranged in the tube body to provide compartments of different sizes, Figs. 30-32 (not shown) These Figures illustrate alternative longitudinal seam arrangements, but each show that at least one raw edge of the sheet is located externally to the formed compartments to avoid contact with the intended contents. Reference is made to Specifications 1,491,053 and 1,491,054.

Title: Process for the Deep Drawing of Hollow Objects from Blanks and Blank Holder and Drawing Ring for Carrying out the said Process
IPC: B21D22/22

Abstract: 1,195,278. Stamping. NETHERLANDS, APPLIED SCIENTIFIC RESEARCH FOR INDUSTRY, TRADE & COMMERCE. 30 Oct., 1967 [31 Oct., 1966], No. 49170/67. Heading B3Q. Apparatus for deep drawing circular, square &c., blanks to form cylindrical articles or articles having a rectangular, square, elliptical &c., cross-section comprises a drawing ring 3, Fig. 3, having a ribbed upper surface and a hold-down 2, Fig. 2, with a corresponding profile and an allowance for the thickness of the blank. As illustrated, the hold-down 2 has a flat base surface 4 and four projections 7 forming part of a concave conical surface. Surfaces 11 between the ribs 14 of the drawing ring are part of a convex conical surface. The arms 14 protrude less than the projections 7. Instead of a plane base 4, it may be conical, the upper surface 14 then being conical or flat. The flanks 16, 9 may be parallel or convergent, and the ring may have six ribs 13. Exchangeable ribs 13 and projections 7 may be used experimentally to determine the best shape for a particular article. Operation.-The ribs and projections divide a blank into zones engaged by the ribs 13 and zones engaged by the projections 7, the zones being separated by axially-bent sections of the blank which, during descent of the drawing punch (not shown), increase tangential compression and thus radial extension in the zones engaged by the projections. This property is utilized in drawing square blanks by positioning the diagonals of the blank on the ribs 13 where they are substantially free from tangential deformation. If the material of the blank is liable to form ears, due to having different yielding properties in different directions, the blanks should be so cut that ear formation occurs between the corners. Round blanks of earforming material should be located so that any ears are formed over the ribs 13.

Abstract: 1285985 Acoustic measurement of rock characteristics SOC NATIONALE DES PETROLES D'AQUITAINE 27 Oct 1969 [11 Dec 1968 30 Dec 1968 27 Feb 1969] 52545/69 Heading H4D [Also in Division G1] The characteristics of rock are measured during drilling as a function of the drilling depth by sensing vibrations of the drilling gear, clipping the electric signal thereby obtained to limit its voltage to between two predetermined values, passing the resulting signal through a band pass filter centred on a frequency equal to the frequency of rotation of the tool times the number of attacking elements on the tool, measuring the amplitude of the resulting signal and recording it on a chart driven in accordance with the drilling depth. Longitudinal and/or torsional vibrations may be sensed.  As shown in Fig. 2, a sleeve 21 for connection in the drilling chain between the driving rod (9, Fig. 1, not shown) and the sludge injection head (7) carries two quartz accelerometers 31, 36 mounted diametrically opposite and axially offset as shown to respond to longitudinal vibrations. The accelerometers are connected via F.E.T.s 32, 37, slip rings 25 and brushes 27 to the clipping and filtering circuits (15). In a modification (Fig. 3, not shown) longitudinal vibrations are sensed by strain guages (47, 48) connected in a bridge circuit with compensating strain gauges (49, 50). Accelerometers or strain gauges may be mounted in recesses at the lower end of the driving rod (9). As shown in Fig. 8, strain gauges 123, 124 and accelerometers 125, 126, 127 are mounted on a sleeve at the bottom of the drill chain near the tool. Sludge pumped down the centre of the drill chain drives a turbine 135 to supply electricity to the clipping and filtering circuit 119, the output of which is arranged to operate a valve 117 to transmit pressure pulses through the sludge to a pressure detector (104, Fig. 7, not shown) and radio transmitter (114) at the top of the borehole. Accelerometer 127 senses the frequency of rotation of the drill and may be used to control the centre frequency of the band pass filter (Figs. 9, 10, not shown). Strain gauges 123, 124 enable longitudinal or torsional vibrations to be selected for measurement. Circuit details.-The voltage clipping circuit (Fig. 4, not shown) comprises a differential amplifier (56) having a diode connected across its input terminals, and a feedback circuit including pairs of oppositely poled, parallel connected diodes and a R.C. circuit for alternating high frequencies. An amplifier, band-pass filter and rectifier circuit are described with reference to Fig. 5 (not shown). The rate of drilling may be automatically controlled in dependence on the measured characteristics of the rock.
